 150 TItE CONDOR Vol. XIV Phasianus torquatus. Admitted by Cooke in 18)8 and omitted by Sclater in 1912. Sclater's action is correct as the bird was an introduced species,- though both Cooke and $clater admit the English Sparrow to the State list. Buteo lineatus olegans. Omitted by Sclater since it was based on a sight idcntification. Otus asio asio. Omitted by Sclater. This species was admitted to the Colorado list c,n the strength of the statement by Snyder that he had once cap- tnred one in the mottled phase near Greeley. As dichromatism is not known in either of the screech owls that are resident in Colorado, a bird in the red phase would seem necessarily to be referred to asio. The lately ascertained fact that maxwelliae inhabits the plains to eastern Yuma County, while aikeni ranges east to the Kansas line (Holly, June 2, 1908), makes the probahility much less that asio would ever occur in Colorado. Sphyrapicus varius. Omitted by Sclater. There was a specimen in the Maxwell collection that was identified by Ridgway as the eastern form. At that time it was claimed that every specimen in the collection had been taken in Col> rado, but it has since been learned that some of them were bought from o:tside collectors and it may well be that this particular specimen had been so obtained. All other records for the eastern form in Colorado are now known to be errors and Sclater is undoubtedly justified in dropping it froin the list. Muscivora forficata. Omitted by Sclater because it was based on a sight identification. The species is, however, so peculiar in shape and actions and was so distinctly seen by the observer that there cannot well be a mistake in the iden- tification. Otocoris alpestris praticola. Omitted by Sclater, though its claim to a place in the list is exactly the same as that of enthymia which is admitted. Junco hyemalis oreganus. Omitted by Sclater, though the specimen was identified by Ridgway and the record has been published (Auk, xxv, 1_c/0, 187: Auk xxvL 1909, 417). Junco hyemalis rnontanus. Junco hyernalis annectens. Both omitted by Sclater on the ground that they are probably hybrids instead of geographical races. While the present writer frankly admits that the last word on the junco question has not yet been written and that this final judgment probably will be radically different from the treat- ment of the snbject in the present edition of the A. O. U. Check-List, yet the tendency of the later discoveries in regard to breeding ranges is strongly against the theory of hybridization. Vermivora celata lutescons. Omitted by Sclater who consider that all Colorado orange-crowned warblers should be included tinder the name celata. While probably all the breeding birds of the State are the same form, yet it would be strange if some of the more western breeding birds of lutescens did not pass through Colorado during migration. Indeed, specimens of such mi- grants have been so identified by Ridgway (Nidologist, , 1896, 76). In this connection it is interesting to note that if Oberholser's name orestera is ever adopted for the breeding birds of the Rocky Mountains, it will still be necessary to retain celata in the Colorado list as a rare straggler based on a specimen taken September 18, 1910, at Boulder by N deW. Betts and identified at the Bio- logical Survey. Geothlypis trichas. Omitted by Sclater, and correctly, for the specimen on which Cooke's original record was based has since been examined at the Biological Survey and found to be occideutalis.
